A happy-go-lucky blue girl from Vermont who defines The Pollyanna. She unknowingly makes Vendetta look foolish and incompetent, so Vendetta plots to kill her. Despite her naivete and obliviousness, Charlotte always avoids certain death. In case you haven't figured out yet, she drives Vendetta insane. Voiced by Amy Winfrey.

- Cheerful Child
- Cloud Cuckoolander
- The Ditz
- Does Not Like Spam: Strawberries are one of the few things in this world she cannot stand.
- Expy: Of Lulu.
- Flanderization/Characterization Marches On: Hit hardest. She gets dumber, more optimistic, and more invincible as the show goes on.
- Fluffy Tamer: She tamed the scissor fiend into being her pet.
- The Fool
- Genki Girl
- Girly Girl: She loves rainbows, cute animals, baking cupcakes, dancing, singing, the color pink, and makeovers.
- Hair Decorations: A bow.
- Identical Granddaughter: To Charlene.
- Innocent Blue Eyes: Sort of.
- Insult Backfire: Vendetta constantly tries to insult her, but she always takes it as a compliment. Taking it further, she mistakes projectiles thrown at her as gifts.
- Na´ve Newcomer
- Perpetual Smiler
- Parental Abandonment: Her grandmother says they're astronauts. We don't know for sure what happened to them.
- The Pollyanna: Her defining trait.
- Precious Puppy: She looooves puppies.
- Raised by Grandparents: In the TV series, she's shown to be raised by her grandmother Charlene.
- Stupid Good
- Super Not-Drowning Skills: "I can hold my breath for niiine hours!"
- True Blue Femininity
- Vocal Evolution: In the TV series it's more obvious she's voiced by a woman in her thirties. She sounds like a child again in the most recent web episode (made for 2012 April Fool's Day), so it could just be the mic. Or the dialogue for that episode was recorded years ago.
A wicked young girl who makes monsters, called "fiends", from a recipe book and uses them to take control of Clamburg. She spends her time tormenting the residents, especially her classmates, into submission. Voiced by Aglaia Mortcheva.
- Art Evolution: Much more symmetrical in the TV series.
- Asshole Victim: Of Charlotte's antics.
- Bad Is Good and Good Is Bad: So much that she absolutely hates the idea of having a shred of good in her.
- Big "NO!"
- Card-Carrying Villain: An exaggerated example. She is obsessed with being as vile as humanly possible and feels good by doing bad.
- Character Exaggeration: In the TV series, she's a little more of a bitch, taking more pleasure in her villainy, and tosses out the word "stupid" much more often.
- Clint Squint
- Comedic Sociopath
- Creepy Child
- Deadpan Snarker: Her attempts often fail though.
- Drama Queen
- Even Evil Has Loved Ones: She keeps her parents as shrinked pets in a hamster cage. While this could be seen as mere cruelty, it is implied that she cares about them in her own twisted way. The thing is, she is such a Card-Carrying Villain, she can't bring herself close to admitting it, even to herself.
- Even the Girls Want Her: A possible interpretation. Charlotte, Marion and Rubella all showed a rather close interest in her.
- Enfant Terrible
- Evil Is Hammy
- Evil Is Petty
- Expressive Hair: Her pigtails fly up when she yells.
- Giggling Villain: "Hee hee heh heh heh...hahaha."
- Girlish Pigtails
- It's All About Me
- Lean and Mean: Ironically...
- Mad Scientist
- Meaningful Name
- Names to Run Away from Really Fast
- Never Say "Die": Almost always says "I will destroy you!". In the web series, the only time she doesn't is when she thinks she's in hell. She uses "dead" more often in the TV series.
- Narcissist: She even has pictures of herself all over her house's walls.
- Nightmare Fetishist
- Pet the Dog: Strongly averted in her case. Just tell yourself that any time it looks like Vendetta's actually doing something nice for somebody, there is always a sinister ulterior motive. Though the fact that she keeps her parents alive might mean something.
- Real Men Hate Sugar: A female example in the TV series. She hates cookies, gumdrops, and if she's eating ice cream, it has clams in it.
- Sickly Green Glow
- Slasher Smile: Pulls one in "Super Evil" when trying to learn one of Charlotte's "evil" ways - giving out cookies with a smile.
- Trademark Favorite Food: Clams, beef jerky, grape punch.
- Tsurime Eyes: Puts on this appearance with her constant angry squinting, but her eyes are actually as large and round as the other characters'.
- Villain Decay: Invoked.
- Villain Protagonist: It's difficult to say whether Charlotte or Vendetta is the protagonist, but Vendetta seems to get more focus.
- Why Did It Have to Be Snakes?: Her hatred of music in the last three web episodes is more like a phobia than anything.
- You No Take Candle: Messes up her English sometimes, especially in the web series. Whether this was intentional or an issue with her voice actress is unknown.

- Flanderization: His sensitive traits, devotion and submission to Vendetta are more apparent in the web series finale and the TV show.
- I Am Not Weasel: He's a giant hamster. He's been mistaken for a bear and a dog.

- Non-Human Sidekick
- Punch Clock Villain
- Rodents of Unusual Size
- Trademark Favorite Food: Like Vendetta, clams, beef jerky and grape punch.
- The Unintelligible: Speaks exclusively in grunts.
- Intelligible Unintelligible: Vendetta seems to understand him, to an extent.
Scissor Fiend / Buttons II
A small black fiend with a beak that works like extreme scissors, cutting through anything. In the web series, this is the first fiend Vendetta makes for the intention of killing Charlotte.
- Bad Powers, Bad Fiend: Subverted. It may have sliced Charlotte's house in half, but it turns out to be very caring towards both Charlotte and Vendetta, and very talented at making paper snowflakes.
- Dark Is Not Evil
- Feathered Fiend: May not have feathers, but it's definitely a fiend, and it's shaped like a bird. Subverted as it eventually becomes a tame pet of Charlotte's.
- Precious Puppy: What Charlotte thinks it is.
A giant red cat, said to be the first fiend Vendetta made. Voiced by Amy Winfrey.

- Dumb Muscle
- Extreme Omnivore: For starters, she eats her desk on introduction.

Vendetta's parents in the TV series. They have been shrunken down to fit into a hamster cage. Voiced by Dave Wasson and Aglaia Mortcheva.
- Funny Foreigners
- Incredible Shrinking Parents
- Regional Riff
- Strong Family Resemblance: Vendetta takes after her mother.
- Trademark Favorite Food: Viktor likes sausages and cheese.
Stated by Charlene to be astronauts. They may have actually died.
A beige man who's the schoolteacher of room 4, though he never gets the opportunity to actually teach anything. He's the most fearful of Vendetta, and has a red Toothy Bird keeping him in check. Voiced by Peter Merryman.
- Expressive Hair: Almost completely bald, but has a few hairs on his head that stick up when he's scared or nervous.
- Expy: Amy Winfrey worked on South Park before starting her web projects, and Mr. Milk looks very similar to Mr. Garrison. His personality is the very opposite, however.
- Extreme Doormat
- Hidden Depths: Web episode 14 and "Swiss Banker" shows he has a very nice tenor singing voice.
- Long Pants
- Shrinking Violet: Rare male example.
- Vague Age: Is he elderly? Middle-aged? A young man who lost his hair from stress? His crush on Ms. Minty in the TV series would most likely place him as one of the former two.
The nervous pale blue girl who sits next to Charlotte. She was the first to warn Charlotte of Vendetta. Voiced by Amy Winfrey.
- Cloud Cuckoo Lander: In a web episode commentary (that you can't see unless you won the Making Fiends Art Contest) she believes her glass animals can talk and eat.
- Fat Girl
- Hidden Depths: The TV series shows she's been planning to escape Clamburg for years.
- Huge Schoolgirl: She was an overweight girl of typical height in the webtoon, but in the TV series she towers over every student except for Marvin, and he's very skinny.
- Odango Hair
- Parental Abandonment: We never see her parents. Which may explain a few things.
- Screaming Woman: Her main role in the web series, where she would go "EEEEEEEE!". Her scream in the TV series is more like "Aaaaaugh!", probably because she sounded too similar to Charlotte's hamster, Buttons.
- Shrinking Violet
The first student to appear. He gives Charlotte dire cautions about Vendetta and her fiends, but she doesn't understand him and ignores them. He and his family are Puritans. Voiced by Peter Merryman.
- Adaptation Dye-Job: Grey -> purple.
- Born in the Wrong Century
- Charlie Brown Baldness

- Tareme Eyes

- Adaptation Dye-Job: He's brighter and greener in the TV series.
- A Day in the Limelight: "Marvin the Middle Manager".

- Ambiguous Disorder: He doesn't pay attention in class, acts kind of dumb, is easy to control...he could have a learning disability.
- Annoying Younger Sibling: According to his Nick bio, he has eight of them.
- Butt Monkey
- Disappeared Dad: In "Parents" we only see his mother. Marion mentions his father in her webtoon DVD commentary, saying his father works in a factory that puts stickers on bananas (which is why Marvin brought a banana to Show and Tell) but that commentary also showed Marion was an extreme Cloud Cuckoo Lander. Either way, this may have all been retconned.
- Ow, My Body Part!: His Catch Phrase is "My __!" Once it was "My pencil!"
- Unlucky Everydude
- Verbal Tic: He'll always start with his sentences with "my".

- Cloudcuckoo Lander: According to his Nick bio.
